The vehicle gasoline fuel system is not working until it completely stalled. During the time that the gas fuel system is not functioning, i run the vehicle using purely lpg. But when the complete stall happened, even the lpg kit is not functioning.

From the diagnosis and check ups by a reputable Mitsubishi authorized shop electrician/mechanic, the malfunctioned gasoline fuel system was brought by an overheated fuel pump which almost burned the entire vehicle (Mitsubishi Adventure gasoline). The entire fuel asssembly was burned which prompted me to replaced it with an OEM materials. The worsiest thing discovered is that the computer box was also damaged because of the electrical damaged at the fuel pump assembly.

Buti na lang, the worst thing did not happen to me and my family. God Blessings.

What prompted the gas fuel pump to overheat? Maybe sir Mike and other lpg conversion gurus can help me.

Is the fuel pump remains at "ON" mode even when we are running on LPG? According to the LPG mechanic who visited the vehicle when it stalled, he mentioned that they are presently installing relays so that the fuel pump will only function when in gas mode.

I hate to think that these worst things happens because of my conversion. I ended up losing a lot than saving a little. At present, im looking for a computer box for which we know will cost a lot.

Thanks for raising issues mentioned above

First of all let me allay your fear that the fuel pump can cause burning of your vehicle cause it will not. The fuel pump may have been damaged not because of overworking as in normal running condition it is suppose to work all the time. The fuel pump condition might have been caused by dirty fuel or possibly because at one time or another your gas tank was running empty and thus the fuel pump was damaged.

Second you mentioned that you had trouble with your fuel pump earlier on but your vehicle continues to run on lpg. If this is the case then your check engine might have lit up. If it did not then you must have had a bad computer box to begin with.

Third at customers option we do put relay on the vehicle fuel pump however this is not necessary. As a matter of fact most of the vehicles converted do not have a relay installed and yet they work fine up to this day. This includes my CRV and X trail which has been running for more than two years on lpg. Even taxis who on average clock in 100,000K /year have been running without fuel relays for two plus years now. Even if you ask other auto-lpg installers fuel relays are not a standard.



Please let me know about your vehicle and I would suggest you get a second opinion. As you know even if we go to an authorized service centre the diagnosis might differ from one service centre to another. This has happened to me several times. And in most cases the most convenient excuse is anything foreign inside the engine bay.
